SCIF depends on IOVA which requires IOMMU_SUPPORT to be enabled. The long term fix is to move IOVA from drivers/iommu to lib/ but this current patch should fix the reported issue.

This option is selected by any driver which registers a

device or driver on the MIC Bus, such as CONFIG_INTEL_MIC_HOST,

CONFIG_INTEL_MIC_CARD, CONFIG_INTEL_MIC_X100_DMA etc.

If you are building a host/card kernel with an Intel MIC device
|
|
then say M (recommended) or Y, else say N. If unsure say N.

More information about the Intel MIC family as well as the Linux

OS and tools for MIC to use with this driver are available from
